=================
Tested on linux and OS X
So this is a super simple parser example. The tutorial is located here: link
Between the tutorial and the code you should be able to get started with more advanced projects using C++ and Flex/Bison. Admittedly the example itself is a bit contrived, however it's mean to be simple and get the point across. If there are changes in Flex/Bison that prevent the example from compiling or if you just have improvements, feel free to generate a pull request or just shoot me an e-mail.
To compile just download and run make, there's a super simple test harness to make sure it runs in the test dir.
Or you use CMake.
mkdir build/
cmake ..
make
or with clang
mkdir build/
CC=clang CXX=clang++ cmake ..
make
or with clang with optimisations
mkdir build/
CC=clang CXX=clang++ cmake .. -DCMAKE_BUILD_TYPE=Release
make
To run the simple test after make call
ctest
- OS X Users I've heard of some issues compiling if you've installed
command line tools, then XCode.app afterwards on Catalina (with bash). When compiling with
clang++, the C++ header files aren't found. If you have this issue, exporting an environment variable, such as this,export CXX=/usr/bin/clang++, seems to be a workaround. If anybody has a better solution (aside from wiping out all build tools and reinstalling) please let me know. - Bison Version - updated the latest head to test with Bison vs. 3.5, there were a few minor changes in syntax, now reflected in the example code. Will no longer work with Bison vs. < 3.3, see notes from link.
Thanks!
